Strategy:
 Mass percentage (w/w%) is calculated by dividing the mass of the solute by the total mass of the solution (solute + solvent) and multiplying by 100.

Step 1: Calculate masses
- Mass of ethyl alcohol = 
- Mass of water = 
- Total mass of solution

Step 2: Calculate mass %

Nearest integer: 22.
